HEAT-RADIATOR.

Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed December 26, 1912, Serial No. 788,636. Renewed June 29, 1916. Serial No. 106,727.

To all whom it may concern:

Be it known that I, HARnisoN H. Coon, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented a certain new and useful Improvement in Heat- Radiators, of which the following is a specilication.

My invention relates to improvements in heat radiators.

It relates particularly to heat radiators which employ steam to heat them.

My invention is particularly adapted to be used for heating incubators. An ordinary radiator, which is heated by steam, is unsuitable for use in an incubator, due to inequalities in the distribution of the heat, the part of the radiator at which the intake of steam is effected being heated to a much greater degree than are parts of the radiator through which the steam passes and which are remote from the place of intake of the steam.

I have found that by mixing air and steam together the volume of heating medium is increased and its intensity is reduced over that of'steam alone. I have also found that by having the radiator arranged so that the passage therethrough of the mixed steam and air may be effected principally by natural draft, all parts of the radiator will be heated to substantially the same temperature. thereby effecting an even radiation of heat from the different parts of the radiaton.

My invention has for its object the pro-- viding of a radiator which will embody the principles hereinbefore referred to.

My invention provides further, novel mechanism by means of which the passage of the mixed steam and air through that portion of the radiator which is employed for radiating purposes may be automatically regulated and controlled.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred embodiment of my inventionFigure 1 is a view of my improved heat radiator, shown partly in side elevation and partly in vertical section. Fig. 2 is an end elevation of the same, the

support for the thermostat being shown in vertical section.

Similar characters of reference designate similar parts in the different views.

1 designates a radiating coil, consisting of a series of horizontal convolutions disposed successively at different elevations, the upper convolution being provided at its discharge end with a vertical extension 2, having an outlet at its upper end. The lower convolution of the coil 1, at its intake end, is provided with a downwardly extending portion 3, having an open lower end which serves as an inlet for air, which is mixed with steam, preferably live steam, which issues from a nozzle l, disposed within but not filling the inlet of the portion 3, as shown in Fig. 1.

The nozzle 4 is disposed vertically with its lower end connected to a valve casing 5, in

which is located a valve 6. The valve casing 5 is connected to a lateral branch 7 of a steam pipe 8, which in turn is connected to a steam generator, not shown.

Intermediate of the inlet and outlet of the radiator, and located preferably adjacent to the upper end of the portion 3, is a vertical discharge opening 9, adapted to be more or less closed by means of a damper 10, which is supported by a vertical rod 11, the upper end of which is pivoted to a horizontal lever 12, adjacent to one end thereof, the other end of the lever being supported by a horizontal pivot pin 13, which is mounted in a vertical bar 14:, the lower end of which is secured to the lower convolution of the coil 1.

'15 designates an ordinary thermostat, which upon being heated, has its upper portion moved upwardly, thereby upwardly moving a vertical rod 16, the lower end of which is supported upon the upper portion of the thermostat 15, and the upper end of which has resting upon it the lower edge of the lever 12. The thermostat 15 is mountedupon any suitable support 17.

In the operation of my invention the valve 6 is opened, thereby permitting steam to pass through the nozz e 4 into the Vertical portion 8 of the radiator. Preferably, the upper end of the portion 2 of the radiator is located at a height sufiicient to effect a natural draft through the coil 1, thereby efiecting a flow upwardly through said coil of mixed air and steam, the air being drawn through the inlet end of the portion 3. The mixed steam and air provides a heating medium which has greater volume but less intensity than the steam alone would have. This, in addition to the fact that the flow through the coil is effected principally by natural draft, results in an equable heating of the radiator coil 1 throughout its length, thereby effecting an equal radiation from the different parts of the radiator coil. As the air adjacent to the coil 1 becomes heated, the thermostat 15, being located adjacent to said coil, is caused to expand and through the intermediacy of the rods 16 and 11, and the lever 12, efiects a lifting of the damper 10 from the discharge opening 9, thus permitting the mixed steam and air or a part of it, to pass through said discharge opening so that its heat is not imparted to the convolutions of the coil 1.

When the temperature of the air adjacent to the thermostat 15 is reduced the thermostat will be contracted, thereby permitting the lever 12 to swing by gravity downwardly so as to eflect a closing of the discharge opening 9 by the damper 10. This will cause an increased amount of mixed steam and air to pass through the convolutions of the coil 1, whereby the radiation of heat from said coil to the surrounding atmosphere will be correspondingly increased, which increase of temperature will be communicated to the thermostat 15, thus effecting a rising movement of ,the damper 10, in the manner already described.

From the above description it will be understood that the heating of the coil 1 will be automatic and that it will be heated evenly throughout and kept at a. substantially uniform temperature, which features render the device particularly well adapted for maintaining the uniform temperature required in an incubator.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thus described my invention,

i What I claim and desire to secure by Letters Patent, is

1. A heat radiator having an inlet for air mixed with steam, means by which steam is discharged at relatively low pressure into said inlet and mixed with relatively cold air passing therethrough, the radiator having an outlet for the mixed air and steam disposed at a greater elevation than said inlet, the inlet and outlet both being open to the atmosphere.

2. A heat radiator having a coil provided with an inlet and an outlet for steam and air, the convolutions of the coil being disposed in increasing elevations from the inlet end toward the outlet end, and means by which steam is discharged at relatively low pressure into the inlet and mixed with relatively cold air passing therethrough, the inlet and outlet both being open to the atmosphere.

3. A heat radiator comprising a conduit having an inlet and an outlet both open to the atmosphere and relatively so arranged that fluid is circulated through the conduit by natural draft, and means for supplying the inlet with steam at relatively low pressure mixed with relatively cold air.

4. A heat radiator having a conduit provided with an air inlet and an outlet and having a discharge opening intermediate of the inlet and outlet, means for supplying said air inlet with steam at relatively low pressure to be mixed with air entering therethrough, and means for controlling the discharge through said discharge opening.

5. A heat radiator having an air inlet and an outlet, the outlet being disposed higher than the inlet, and the radiator having a discharge opening intermediate of the inlet and outlet. means for supplying the air inlet with steam at relatively low pressure to be mixed With air entering therethrough, and means for controlling the discharge through said discharge opening.

In testimony whereof I have signed my name to this specification'in presence of two subscribing witnesses.
